Brian,

Thanks for explaining - I now see exactly what you mean, this method would be an excellent way to make gears (and even I could grind the correct shape cutter).  ;D
This would simplify things a lot as only one cutter would be required for each D.P. of gear.

A little further down the line you may want to implement the Auto Tool Zero function using a touch plate.

A search of the forum for 'touch plate' should bring up all the details of what others have done here. It is a worthwhile addition to any machine which I would not be without now.

John,

Have you set the Motor Outputs in the Ports & Pins section ?.

btw. Welcome to the forum.

Brian,

As I mentioned earlier in this thread, the cutter shape would have to be different for each gear having a different number of teeth.

Quote
This is because the gear tooth profile and, more importantly, the shape of the gap between the teeth (and therefore the final shape of the endmill cutter) will be different for any given diameter / number of teeth and the contact angle of the gear (the portion of the involute curve forming the tooth profile is always linked to the pitch circle diameter of the gear).

Brilliant my friend - Everything is here on the forum and you took the trouble to look for the solution.  :)

If only I could solve the E1P1 /E1P0 problem that way  :'(

Thanks Sam.

Congrats on your build and first movements.

I remember the feeling well - just like awaiting the arrival of the first child.  ;D

Hey Guys,

Just as a by the way thing....... If the command E1P0 is changed to E1P0M5 then the code runs perfectly every time on the few examples I have tested - But the turn off delay is increased again almost up to the levels of the M10P1.
Don't suppose this helps but thought I would mention it.

Now only question is how hard is it to assemble and properly home X, Y, Z axis on the Zen toolworks machine!

Hi and welcome to the forum.
Things are only hard to do when you don't know how. If you have any problems someone here will know the answer and everything will be easy  ;)

Thanks Ian,

Due to location of my equipment I am unable to measure the pulse timing at present but I would be most interested to know what it is.

M10 and Z control files attached.
(I am changing the Z dir pin, in ports and pins/motor outputs, to my laser trigger pin16).
